Better than Poly
Perfect protection for Late Silver-Age through modern comics. Crystal clear and easy to use. Since I do NOT use tape around my comics (I don't allow tape in the SAME ROOM as my comics!) I have discovered that simple "Post-It" notes are perfect for closing the flap on these sleeves and pose no danger to the comics. (Unlike Tape, which has destroyed many covers!) These Mylar sleeves are far superior to the standard Poly sleeves and do not need to be changed every few years. The poly sleeves are great for short-term storage, but these Mylar do not wrinkle or start to decay and "out-gas"! If you are storing your' personal collection, for the long-term, THESE are what you want!
